public class FindWithCapabilities extends java.lang.Object implements OptionHandler, CapabilitiesHandler, RevisionHandler
Locates all classes with certain capabilities. One should keep in mind, that works only with the default capabilities of a scheme and doesn't take dependencies into account. E.g., a meta-classifier that could have a base classifier handling numeric classes, but by default uses one with a nominal class, will never show up in a search for schemes that handle numeric classes. Valid options are:All class and attribute options can be prefixed with 'not', e.g., '-not-numeric-class'. This makes sure that the returned schemes 'cannot' handle numeric classes.
-num-instances <num> The minimum number of instances (default 1).
-unary-class Must handle unray classes.
-binary-class Must handle binary classes.
-nominal-class Must handle nominal classes.
-numeric-class Must handle numeric classes.
-string-class Must handle string classes.
-date-class Must handle date classes.
-relational-class Must handle relational classes.
-missing-class-values Must handle missing class values.
-no-class Doesn't need a class.
-unary-atts Must handle unary attributes.
-binary-atts Must handle binary attributes.
-nominal-atts Must handle nominal attributes.
-numeric-atts Must handle numeric attributes.
-string-atts Must handle string attributes.
-date-atts Must handle date attributes.
-relational-atts Must handle relational attributes.
-missing-att-values Must handle missing attribute values.
-only-multiinstance Must handle multi-instance data.
-W <classname> The Capabilities handler to base the handling on. The other parameters can be used to override the ones determined from the handler. Additional parameters for handler can be passed on after the '--'. Either '-W' or '-t' can be used.
-t <file> The dataset to base the capabilities on. The other parameters can be used to override the ones determined from the handler. Either '-t' or '-W' can be used.
-c <num> The index of the class attribute, -1 for none. 'first' and 'last' are also valid. Only in conjunction with option '-t'.
-superclass Superclass to look for in the packages.
-packages Comma-separated list of packages to search in.
-generic Retrieves the package list from the GenericPropertiesCreator for the given superclass. (overrides -packages <list>).
-misses Also prints the classname that didn't match the criteria.
